Dr. O'Connor is simply phenomenal! Our daughter had been suffering from back problems for years and he was the only one who accurately diagnosed and fixed her problem. With a few sessions of manipulating her back, she no longer suffers from scoliosis. It was truly amazing to see her spine go from curved to straight within a month! This man is Fantastic at diagnosing, takes time with his patience and is genuinely interested in helping people. Wonderful office staff as well!

I have had severe pain in my sub-scapular area, up into my shoulder and down my arm for over 20 years. I was told 14 years ago it was due to scar tissue in my sub-scapular area and underwent physical therapy with no improvement. The pain has been a constant in my life. Dr. O'Connor diagnosed me with a herniated cervical disc at the cervicothoracic junction. With one session, he was able to manipulate my disc back into place. Unbelievably, I no longer suffer from debilitating shoulder pain!!

Brilliant. I looked years for a very gifted doctor who knew his stuff. Much smarter than the other clown doctors (if that's not too strong a word) who looked the part but missed things he caught. Best doctor for general medicine and spinal issues in Solano County hands down! Also don't have to wait a month with other doctors who like to look busy by making patients wait for an appointment.
